Open Container Laws
In the U.S., it is not legal to walk around with an open bottle or can of alcohol. This is very confusing to many Europeans and non-Americans, as it is quite common to relax in a public space outdoors with a beer or wine.
Generational Labels
Many people who are not from the United States are confused about why Americans seem to obsess over generational labels like “millennials,” “Baby boomers,” and “Gen-Z.” Non-Americans see these as very arbitrary and strange to group people together so much just based on age.
